A data storage device comprises a host interface and a storage control system coupled to the host interface. The storage control system is configured to perform a write process to write data to storage in response to one or more write operations received over the host interface from a host, determine a quality of written data produced by the write process; and in response to when the quality of the written data fails to satisfy one or more quality criteria, obtain data parity information to compensate for the quality of the written data and write the data parity information to storage.
